On the topic of negotiations, I would recommend a book “Never Split the difference” by Chris Voss a former FBI hostage negotiator.
He takes you through his own experience of handling various hostage situations, salary negotiations etc.
If you find it annoying behavior on the part of the other party, walk away.
Otherwise, it's a pretty poor book:
"Well, I've got these hostages here, so I suppose the 'how' is up to you."
That’ll make for some spicy firing + public disgrace + jail time if you’re wrong.
